This error is atavistic. When restarting tdm (with the systemd patches), tde_dbus_hardwarecontrol works properly, but on subsequent reboots loading from login, I have experienced the old error: Mar 06 13:31:28 valhalla dbus[176]: [system] Activating service name='org.trinitydesktop.hardwarecontrol' (using servicehelper) Mar 06 13:31:28 valhalla org.trinitydesktop.hardwarecontrol[176]: [tde_dbus_hardwarecontrol] Listening...
